This invention relates to an improved window construction.

Heretofore in the vconventional type of window construction the glasspanes have been held in place by tacks and/or pu-tty. In the removal ofa broken glass in a Window ofsuch conventional construction,` it isnecessary to remove the nails and putty before the broken glass can beremoved and then nails and putty are'again used to Jhold the new pane ofglass in place. A large amount of labor is involved in such an operationand is of such a character that frequently a skilled Worker is calledupon to make the installation.

It is an object of thisinvention to provide a window sash constructionof such a character` that the glass, when broken, mayzbe removed and anew pane installed With a minimum amount of labor, and by any one evenunskilled in the use of putty and in the fit-ting of windows. The windowof my invention is provided with apane of glass slidable in a windowframe so that the glass may be readily slid from the 'frame and a newpane slid into place.

Another object of this invention is to provide a Window sash having anouter frame and an inner frame to which the pane of glass is secured,the inner frame being slidable in the outer frame for the removal of theglass therefrom. By such a construction and arrangement an inner frameof a definite size, having the glass fastened therein, may be procuredby a buyer and slid into place without calling upon one skilled in suchan operation, and the glass may be readily slid into the inner frame.

With the above and other objects in view, my invention consists in thearrangement, combination and details of construction disclosed in thedrawings and specifications, and then more particularly pointed out inthe appended olaims.

In the drawings:

Figure 1 is a front elevation, partly broken away, of a window sashconstructed according to an embodiment of my invention,

Figure 2 is a top plan view, With the cover plate removed,

Figura 3 is a Vertical section taken on the line 3-3 of Fgure 1,

Figure 4 is a horizontal section, partly broken away, taken on the line"i 4 of Figure 1,

Figure 5 is a front plan view, partly broken away, of the inner framewith the glass removed,

Figure G is a horizontal section, taken on the line '6-5 of Figure 1,and

Figure 7 is a Vertical section taken on the line 'i-l of Figure 1.

Referring to the drawings, the numeral I [1 Vdesignates generally awindow sash constructed according to an embodiment of my invention. Thewindow sash 11) is formed With an outer frame I 1, an inner frame 12 anda pane of glass 13. The inner frame 12 consists of an elongated flatlstrip of metal 14 on each side of the pane of glass 13 about the upper,lower and side edges thereof. The frame members 14 overlie the edges ofthe glass '13 and extend outwardly therefrom where the correspondingmembers 14 on opposite sides are secured together by bolts 15. In orc'er:to space' the members 14 apart a distance equal ;to the thickness ofthe glass, washers or spacers 16 are placed about each bolt 15. Theglass 13 is then supported against movement in the frame 12 by thespacers 18.

A lower bar 1'1 is fixed between the framezmembers if Valong the loweredge of the frame 12 `to provide a firm and solid base therefor. Nobolts 15 or spacers 15 are provided on the 'inner frame 12` along theupper edge between the members: 1.4 in order that theglass '13 may beinstalled freely or removed from this. end.

The inner frame 12 and glass 13 are both secured in an outer frame 11.The outer frame 11 is formed with frame members 18, U-shaped incross-section, about the edges of the inner frame 12, the members 14being encompassed between the arms and bight of the members 18, as seenin Figures 4 and 6. The outer frame 11 extends about the upper 'andlower end and sides of the inner frame 12, the top member 18a thereofbeing open along the bight thereof, whereby the inner frame 12 and glass13 may be removed from the outer frame 18 either singularly orassembled. The inner frame 12 is secured to the outer frame I I by bolts19 which extend through the inner frame members 14 outwardly of the paneof glass E3. The lower edges of the inner panel 12 are spaced from theinside of the lower frame members 13 by space bars 21! which extendalong the length thereof.

The inner edges of the outer frame members 18 and 18a are bent inwardlyto press against the glass 33 inwardly of the inner frame 12 to providea Weather seal about the glass 13.

To close the upper end of the frame 11 a cover 2 extends across theopening in the bight of member 13a and is formed with a pair ofd-epending ears 22, one on each side of the outer frame member 13a andis secured in place by a bolt 19a which extends through the ears 22, andthe outer and inner frame members 18a and 14 respectively. The bolt 19a.and cover plate 21 hold the inner asoasss frame l2 and glass 13 in thewindow sash IB, and removal of bolt l9a permits removal of the glass |3from both inner and outer frames 'and its replacement. By removing allthe bolts |9 from the outer frame ll, the inner frame IZ and glass |3may be removed.

Hooks 23 are provided on the outer side of each side member |8 forattaching a chain 24 to which a sash weight, not shown, is secured, anda finger hook 25 is fastened to the inner side of the lower frame member|8 for raising and lowering the window I 0.

I do not mean to confine myself to the exact details of constructionherein disclosed, but claim all variations falling within the purview ofthe appended claims.

What I claim is: l

1. A Window sash comprising an inner frame and an outer frame, saidinner frame including elongated metal strips on both sides of a glasspane about the perimeter thereof, said strips partly overlying the edgeof said pane, means securing the strips on one side of said pane to thecorresponding strip on the other side in spaced apart relation, saidstrips being spaced apart a distance equal to the thickness of saidpane, said outer frame including U-shaped channel members havingencompassing bight portions extending between spaced arms thereof, theinner frame being disposed between the arms of said channel members, theupper of said channel member being formed with an opening therein alongthe bight thereof through which said pane may be slidably engaged, aclosure for said opening and means securing said closure to said outerframe, said means engaging said inner frame and pane for holding saidinner frame and said pane against sliding movement in said Window sash,whereby said pane may be removed upon removal of said means and saidclosure.

2. A window sash as set forth in claim 1 Wherein said channel membersare formed with inwardly bent edges engageable with said pane forsealing said pane in said sash.

3. A window sash comprising an inner frame, a pane of glass verticallyslidable therein, and an outer frame, said inner frame including frontand rear side, top, and bottom members, said members being formed ofelongated metal strips partly overlying the edge of said pane, meansextending through said side members for securing the front and rearmembers together, said means including spacers for retaining said frontand rear side members in spaced apart relation and for preventinghorizontal movement of said pane, a bar disposed between said front andrear bottom members for` retaining said members in spaced apart relationand for supporting said pane, said outer frame including U-shaped side,top and bottom channel members with the bight portions thereof spacedoutwardly from the edge of said pane, the inner frame being disposedbetween the arms of said channel members and spaced therefrom, said topchannel member formed with an opening in the bight portion thereofthrough which said pane may be slidably engaged, a closure for saidopening and means securing said closure to said top channel member, saidsecuring means engaging said inner frame and said pane for holding saidinner frame and said pane against sliding movement in said outer frame,whereby said pane may be removed from said inner and outer frames uponremoval of said securing means and said closure.
